Who is Emil du Bois-Reymond? Information about the physiologist Emil du Bois-Reymond biography, life story and works.

Emil du Bois-ReymondEmil du Bois-Reymond; (1818-1896), German physiologist, who studied the electrical properties of animal tissues. Du Bois-Reymond was born in Berlin on Nov. 7, 1818. He studied anatomy and physiology at the University of Berlin under Johannes Miiller, one of the founders of modern physiology. After writing his graduation thesis on electric fishes, Du Bois-Reymond became interested in the electrical properties of animal tissues. In 1840 he began to refine old instruments and invent new ones with which he might detect the passage of tiny currents of electricity in nerve and muscle tissue. One of his inventions, a type of induction coil, is still used.

Using the improved instruments, Du Bois-Reymond showed that a nerve impulse is accompanied by a change in the electrical condition of the nerve. This finding was, in a way, a return to the idea of “animal electricity,” introduced earlier by Luigi Galvani and subsequently mysticized by Franz Mesmer. However, Du Bois-Reymond’s ideas, accompanied by accurate measurements, upset vitalism by showing that even the subtle action of nerves was amenable to physical study with instruments similar to those used to measure electric currents in wires.

In 1858, Du Bois-Reymond became professor of physiology at the University of Berlin. Although popular with students, he offended many conservative colleagues by his materialistic views and his championship of controversial beliefs. He was an early supporter of Charles Darwin’s theory of evolution by natural selection. Du Bois-Reymond died in Berlin on Dec. 26, 1896.
